Application January 23, 1935, Serial No. 3,013 In Great Britain February 3, 1934 8 Claims.

The object of the present invention is to provide an improved. cardboard box, in which the partition is capable of being folded against thev sides of the box.

The partition may consist of one layer of cardboard, but for a stronger partition two layers of cardboard are employed which then act as a single layer.

According to the present invention the partition has a flap at each vertical edge. The flap at one edge is xed to one side of the box, thus allowing the partition to move upon it as upon a hinge, and the flap at the other free edge is adapted to pass behind a piece of cardboard that is fixed at its upper end to the other side of the box.

If desired the partition may be carried up above the body of the box and be perforated to form a handle.

The invention is illustrated in the accompanying drawing in which:-

Fig. 1 is a plan of a box showing one construction of partition.

Fig. 2 is a section taken on the line 2-2 seen in the direction of the arrow.

Fig. 3 is a section through the partition taken on the line 3--3 of Fig. 1 seen in the direction of the arrow.

Fig. 4 is a section through a box, similar to Fig. 2 showing a modified method of forming a distance piece between the side of the box and a flap upon the partition.

Fig. 5 is a face View and Fig. 6 is an edge View showing a method of forming a simple locking strip to be used in conjunction with a partition made of a single layer of cardboard.

Fig. '7 is a plan of a box, partly broken away, provided with the locking strip shown in Figs. 5 and 6.

Fig. 8 is a section on the line 8-8 of Fig. 7 seen in the direction of the arrow.

The box shown in Fig. 1 has two sides Il and I2 and ends I3, I3. The box has also inner layers of cardboard I4 at its ends as is usual with folding boxes. As the invention is applicable to boxes that are adapted to fold in many wellknown ways, and even to boxes with fixed sides and bottom, no means have been shown for enabling the box to fold.

As shown in Figs. 1, 2 and 3 the partition is made of two layers of cardboard i5, I5. Each layer has a flap I1 at one edge and a iiap I3 at the other edge. The flaps I3 are fixed near their upper and lower ends to the sides II and I2 by means of stitching I9 as shown in Fig. 2. The 5 sides II and I2 are turned over at their upper edges to form distance pieces 20 located between the sides II and I2 and the flaps I8. The other flaps II are adapted to slide between the strips or flaps I8 and the sides of the box, thus se- 10 curing the layers I5 and I6 of the partition close together. The upper edges of the flaps II bear against the distance pieces 20 thus holding each portion of the partition down along that side where it is not hinged to the box. 15

The partition may be carried up above the body of the box as seen in Figs. 2 and 3 and may be cut away at 2| to form a handle. The partition may, however, terminate at the level of the body of the box shown by the broken line 22 shown 20 in Fig. 2.

Instead of turning the edge of the box over as shown in Figs. 1 and 2 the flaps I8 may be cut sufficiently long to allow their upper ends to be turned over to form distance pieces 29 as shown 25 in Fig. 4.

If the partition merely consists of one layer of cardboard I5 as shown in Figs. 7 and 8, its flap I8 is stitched by wire I9 to the side I2 and its ap I'l passes behind the vertical strip 23 shown 30 separately in Figs. 5 and 6. This strip 23 is fastened to the side of the box at its upper and lower ends by wire stitching I9 and is separated from the side of the box by means of the sepa arate distance piece 24. 35

What I claim as my invention is:

1. An improved cardboard box having in combination a body, a partition, a flap at each vertical edge of the partition, one ap being fixed to one side of the body, and a piece of cardboard fastened 40 at its upper end to the other side of the box behind which the other ap passes.

2. An improved cardboard box having in combination a body, a partition, a iiap at each vertical edge of the partition, one flap being xed to one side of the box and adapted to act as a hinge for the partition, and a piece of cardboard xed at its upper end to the other side of the box, the other flap being adapted to pass behind the said piece of cardboard.

3. An improved cardboard box having in combination a body, a partition consisting of two layers of cardboard, a flap at each vertical edge of each layer, one iiap of each layer being fixed to one of the opposite sides of the body and adapted to act as a hinge for its layer, a distance piece between each xed flap and the side of the body, said distance pieces being formed by bending over the upper edges of the sides the body, and the other flap of each layer being adapted to pass behind a xed flap and beneath a distance piece.

4. An improved cardboard box having in combination a body, a partition, a` iiap at each vertical edge of the partition, one flap being xed to one side of the body, and a piece of cardboard fastened at its upper and lower ends to the other side of the box behind which the other iap passes.

5. An improved cardboard box having in combination a body, a partition, a iiap at each vertical edge of the partition, one iiap being fixed to one side of the box and adapted to act as a hinge for the partition, and a piece of cardboard iixed at its upper and lower ends to the other side of the box, the other flap being adapted to pass behind the said piece of cardboard.

6. An improved cardboard box having in combination a body, a partition consisting of two layers of cardboard, a iiap at each vertical edge of each layer, one flap of each layer being iixed at its upper end to one of the opposite sides of the body and adapted to act as a hinge for its layer, the other fiap of each layer being adapted to pass behind the iixed iiap of the other layer.

'7. An improved cardboard box having in combination a body, a partition consisting of two layers of cardboard, aI iiap at each vertical edge of each layer, one ap of each layer being iixed at its upper and lower ends to one of the opposite sides of the body and adapted to act as a hinge for its layer, the other iap of each layer being adapted to pass behind the xed ap of the other layer.

8. An improved cardboard box having in combination a body, a partition consisting of two layers of cardboard, a flap at each vertical edge of each layer, one flap of each layer being xed to one of the oppositeisides of the body and adapted to act as a hinge for its layer, a distance piece 20 fixed between the upper part of each fixed flap and the side of the body to which it is fixed, the other ap of each layer being adapted to pass beneath the distance piece and behind that iixed flap towards which it moves when the layer is 25 being rotated on its hinge into a position at rightangles to the sides of the box substantially as set lforth.
